"method not found in class " error message !

Question

Dear People,
I have an error message that says:
"Clerk.java": Error #: 300 : method doTransaction(stan_ch15p622.Transaction) not found in class stan_ch15p622.Bank at line 36, column 12
below is the Clerk class of the program.
doTransaction() is defined below the constructor and is called at the
bottom of the class.
Thank you in advance
Stan
package stan_From_Ivor_Horton_ch15p622;
public class Clerk implements Runnable
private Bank theBank; // the employer. who the clerk works for
private Transaction inTray; //holds a transaction
public Clerk(Bank theBank)
this.theBank = theBank;
inTray = null; // no transaction initially
//receive a transaction
public void doTransaction(Transaction transaction)
inTray = transaction;
//The working clerk...
public void run()
while(true) // no transaction waiting ?
     while(inTray == null)
     try
     Thread.sleep(150); // then take a break
catch(InterruptedException e)
     System.out.println(e);
     theBank.doTransaction(inTray);
     inTray = null;
//you can check whether a clerk is busy by calling the isBusy() member
// it returns true if the transaction is strill in progress
public boolean isBusy()
return inTray != null;
}

Dear Hambone3,
Due to your help I was able to correct my error. I mispelled the
method in the Bank class. I wrote "toTransaction" instead of
"doTransaction".I have alwyas had a hard time interrpreting the
error messages literally because many times I don't see the
connection between the message and the error. Cold water over
the brain is sometimes what I need.
God bless you.
Stan
